Syllabic nasals How do we treat them Caroline

Syllabic nasals – How do we treat them? Caroline Hattee Cleft Net East

Aims • Study results • Therapy ideas • Diagnostic implications

Study • Retrospective case note review • N= 9 ( 6 non cleft, 2 cleft, 1 SMCP) • Assessed using the STAP and GOSSPASS • Consonant and vowel inventory tabulated and nasality and nasal airflow noted

Subjects

Outcomes • • • Therapy eliminated syllabic nasals in 8/9 cases. 3/9 prolonged therapy 1/9 persisting syllabic nasals 1/9 secondary speech surgery during this treatment period. Close vowels /i, Ì, u/ (and for the diphthongs containing these) tended to respond most quickly to therapy.

Therapy

Vowel Therapy to update input processing Auditory perceptual approaches • Input modelling/vowel bombardment therapy (e. g. Hope cochlear implant ideas hope. cochlearamericas. com) • • Audio and Video therapy e. g. lorry reversing iiii ; u for cow Headphone use as playback in video therapy – optimal proximity of sound

Vowel Therapy to update vowel perception • • • Input : Extended vowel duration (Rusche et al 2004) Increased pitch via Melodic Intonation Therapy (Helfrich-Miller 1984) –counting 1 -6 contains u/i/Ì. Hope cochlear website has good resources in pitch unit section. Output : immediate verbal feedback for each production as “incorrect” placement information or sensory feedback can hamper potential for subsequent target sound production (Ruscello 2008).

Video TK orl

Vowel Therapy Visual feedback • Historical glossometry; speech viewer • EPG • The future - MRI imaging/ultrasound Computer approaches • PC programmes –; SAILS (Rvachew et al 2004) ; Earobics (Earobics cognitive Concepts 2000); Phoneme factory (Wren &Roulstone 2006); Li. PS(Lindamood & Lindamood 1998); Nessy language programme. • Apps available - vowel viz and IPA vowels; cued articulation; vowels central

Apps Vowel viz

Vowel Therapy Linguistic approaches: • Maximal contrast therapy : contrasting open front vowels with close back vowels. • Metaphonological – e. g. The vowel house/Metaphon – visual referent lip rounding vs lip spread • Core vocabulary (Cosbie, et al 2006). • Semantic/rhyme sets e. g. baby/mummy/dummy.

Vowel Therapy Motor approaches • Nuffield production and sequencing (Williams and Stephens 2010). • PROMPT • Cued vowels

Implications for future Practice • • Assess consonants and vowels; notice weak syllables Hearing levels and complexity of speech disorder important prognostic factors – maximise visual and auditory input

Implications for future practice • • • Diagnostic therapy may help differentiate between syllabic nasals and nasalised vowels Syllabic nasals do respond to therapy Detailed notes of therapy aims and methods needed to inform outcome. Ideally video pre and post therapy • SLT Training at undergraduate level • Further research opportunities

Conclusion Geirut 1998 “ direct therapy for vowels can have a positive outcome” But…. . • • Gibbon 2013 “one approach not advocated is non speech oral motor activities as there is no evidence to suggest that these methods are effective”.

Don’t be alarmed – go for it !
